Many people think Taissa Farmiga from ‘The Nun’ and Vera Farmiga from ‘The Conjuring’ are mother and daughter.
In reality, they are sisters with a 21-year age gap between them.
In Pulse (2001), the film's most terrifying ghost was played by ballet dancer Akiko Kitamura, who got the role after telling the director she could move even creepier than Sadako from Ring. That unsettling, glitch-like walk was performed entirely by Kitamura herself with no CGI.
